If the republicans do nothing then that will guarentee the presidency will be retained by the communists and this country ceases to exist.
If the Republicans take the House and Senate next year (and they should), then they can pass a whole passel of bills (and they should). But what president will sign them into law? They can also investigate the hell out of a whole passel of crooked democrats (and they should), but whose DOJ will prosecute?
But the new Republican majority can definitely stop the democrats from further advancing their new green deal socialist agenda (and they should). And they should be able to stop and roll back a whole bunch of obviously unconstitutional crap by using the newly conservative courts (thanks to President Trump).
If we fail to take the house and senate next year and the presidency in 24, we can kiss America goodbye.
